java.lang.Object

com.sap.cloud.sdk.datamodel.messaging.jms.JmsMessagingVdmConverter

@Beta
public class JmsMessagingVdmConverter
extends Object

Generic converter for turning JMS messages into Messaging VDM objects. This relies on MessageFactoryMapper objects to pick the right MessageFactory based on the message type. Multiple MessageFactoryMapper objects can be configured, and each MessageFactoryMapper can have mappings for the same message type. In this case, the mapping of the most recently added MessageFactoryMapper is used.
